AUTOMOBILEHEATER.

Specification of Letters Patent.

a subject of the King of Great Britain, and

.a resident of Saskatoon, in the Province of Saskatchewan and Dominionof Canada,

have invented-a certain new and useful Improvement inAutomobilc-I-leatcrs, of which the following is a specification.

This invention is an improvement in heaters, and has particularreference to a heater forautomobiles controlled. by the exhaust fromthecngine.

An object of the invention is the provision of a heater casingadjustably mounted upon a suitable support in a vehicle,'where' by thesame may be moved to a position preferably beneath'a seat and alsoadjusted in such a manner as to beemployed as a foot warmer.

Another object is to provide a heater casing wherein a system of heatingpipes is connected to the exhaust of the engine and the fi0w' of burntgases through'said pipes.

regulated by a novel valve mechanism controlled by the operator. i

The inventive idea involved is capable of receiving a variety ofmechanical expressions, one of which for the purpose of illustrating theinvention is shown in the accompanying drawings, wherein F'gure 1 is aperspective View of the heater, showing the same applied to a vehicle;.1

Fig. 2 is a similarview showing'the valves for controlling the flow ofthe exhaust from the exhaust pipeto the heater casing;

ing 12 are up urality of spaced heat outlet chambers 13 having suitablecovering 1*}, said chambers having an outlet on one side of the casing11. For the purpose of regulating the amount of heat coming from thechambers 13, t lore is preferal'ily provided a a slide member 13ex'temling longitmlinally of thecasing 11 and mounted in the guideflanges 16 forn' ed thereon. This slide memher is provided in its frontwith a plurality of openings 17 corresponding in number to. p

the number of chambers 13 and said openings are adapted to register withthe outlets of said chanibe rs in order to permit of the 1." heat in thehem-r casing makmgits exit therefrom. Th member 15 is provided with a ia knob or handle 18, which may be grasped by the operator in, order toadjustsaid memher back and f1 llllh in order to regulate the size of theheat exit openings.

As shown in Fig. 1, one of the adjustedposit ons of the heater casing isbeneath the seat 8 the v1 :hicle' and said casing is retained 111 thisposition by means of the straps 19 or 01 her holding devices-which arehinged at 20 to the floor? of said vehicle.

' By hinging the casing 11 through the medium of the str: ps 19, it isreadily apparent that the said rasing may be swung ,from

the heater may tensed as a foot warmer.

In order to circulate the exhaust gases through the heater casing, theexhaustipi'pe '9 is tapped at 21"for the reception ofga vertical tohorzontal position whereupon 1 let end 25 of :;aid pipe terminatesudiecent the inlet or d 23. The pipe 24 is'provided with a. brunch. pipe26 which extends longitudinally of the -heater casing-1 and throughtheseveral chambers 13. vToallow for theadjustmznts of the-heater chamber-Q1 from vertical to horizontal positions and vice versa, the circulatingpipe 24 isjpr'm vided adjacent its inlet and outlet ends the universalcoupling 27 shown in section in Fig. 5. .11 through which theinlet andoutlet ends of the pipe 24 extend are elongated, as shown in Fig. 1 toermit of said adi'uste seen that shou d it The openings 28 in the casing,normally in an opened position;

the branch pipe 22 and is normally in closed position. An angularbracket 31 is secured upon the top of the exhaust pipe J, and haspivoted to a free extremity thereof a double bell-crank lever 32, havingtwo ol' its arms bifurcated at the ends as indicated at Iii-l, one. ofthe bifurcations receiving an arm 2-H which actuates the. valve. 2!),while the other bifurcation receives a pin extension 35 carried by'anarm 36 which operates the valve 30 about its pivot. Connected to theextremity of the third arm of the lJQllC-T'illlli lever 32 is one end.oi a flexible connection #57. which passes over a pulley AS and extendsto a point in the vehicle readily accessible by the operator. A spring2-59 secured to the bell crank lever and to the arm ll holds the valves2-9 and 30 in normal position. it will be seen from this descriptionthat by exerting a pull upon the connection 37, the val ves '29 and 30will be. respectively closed and opened, and the exhaust gases will heshunted through the circulating pipe 24 in the heater casing; \Vhen theconnection 37 is released the valves are returned to normal position bythe spring 39;
